1.11 Connection technique
Explosion hazard due to improper handling dur-
ing the connection of the motor!
DANGER
●
Make sure that the motor is only connected in the de-energized state and a
non-explosive atmosphere.
●
Before working on the system, always use a suitable measuring instrument
(e.g. multimeter) to check whether parts are still under a residual voltage
(e.g. due to the residual energies of capacitors in filters, drive devices, etc.);
let their discharge times elapse.
●
The connection between the grounding conductor and the system ground
must be made before any other connections.
●
The junctions to or on the control device must be situated outside a hazard-
ous area or be licensed for the use in hazardous areas.
The motors must be grounded via a motor cable and via a second separate
ground conductor with minimum 4 mm² cross section (refer to
"Connect equipotential bonding conductor" on page 15
Proceed the following connections for safe motor operation:
●
Power connection (inkl. Temperatursensor und Holding brake)
●
Encoder connection
●
Connection of equipotential bonding conductor (acc. to EN 60079-0)
1.11.1 Power connection and encoder connection
Damage to persons or property by disconnect-
ing or connecting energized connectors!
WARNING
●
Connect and disconnect connectors only when they are dry and de-energized.
●
During operation of the system, all connectors must be securely tightened.
Connect flange socket
Proceed as follows to connect the threaded connectors:
1. Place the power connector on the thread of the terminal box in the correct
position.
2. Tighten the cap nut of the power connector by hand. By feeding more ca-
ble, the power connector can be brought up to its end position.
3. Tighten the cap nut up to the stop.
